Audio Troubleshooting
The default EDID for input boards only supports 2 channel L-PCM audio. If a source chooses to ignore this EDID and send a
format that is not in the EDID, the audio may not pass through the Enova DGX at all or it may be distorted.
To present other types of audio formats to the source, a different EDID must be loaded (see the AMX EDID Library at
www.amx.com (search for EDID Library).
If after changing the EDID on the input board, the audio is still distorted or is not present on the destination device, then
the device may not be capable of supporting the requested audio format with the newly loaded EDID setting. In this
case, a standard EDID should be used and the sources set up to only pass the type of audio that the downstream
destination devices can handle.
Checking for Support
One way to check if a destination supports a particular type of audio format is to capture the EDID using DGX
Configuration software’s EDID Programmer tab and paste the EDID data into a free-ware EDID reader program (e.g.,
www.edidreader.com).
For additional information and a table showing which types of audio the different types of boards support, see page 101.
Device Between HDMI Output Board and Monitor
Sometimes a device (e.g., a video processor) between a DGX HDMI Output Board and the destination monitor is
intentionally installed to alter the image scale. If that is not the case and you have image problems, you need to be
aware that the scaler override function is responding to the EDID from the extra device rather than from the monitor. One
possible solution is to use the DGX Configuration Software to read and save the EDID directly from the monitor and then
apply the override values to the output (directions follow).
Reading EDID Directly From Monitor And Applying Override Values To Output
1.
Remove the device between the output and the monitor.
2.
Connect the output directly to the monitor.
3.
Install and open DGX Configuration Software (see page 270).
4.
Select the Scaler Override tab.
5.
Under EDID Source, select the Enclosure and select the Output number connected to the desired destination from
the drop-down lists.
6.
Click Refresh EDID.
7.
From the File menu, select Save to File and save the settings to a file.
8.
Replace the device between the output and the monitor.
9.
From the File menu, select Open File and open the previously saved file.
10.
Click Apply to transmit the settings in the file to the output. This action is temporary until the settings are stored on the
connector in Step 12. Otherwise, the settings last only until power is cycled. The display re-syncs with the output.
11.
Verify that the display is satisfactory before proceeding.
12.
Click Save to store the currently displayed settings to the connector and persist them in memory. If the settings have
been changed since clicking Apply, the newest settings will be saved.
